Hey, all
I am trying to setup a mailserver on a new internet connection. The
domain has been registered, and I have a static IP. If I try and send
mail to the new domain, the mail bounces, and I get a message like:
Recipient address: me@newdomain.com
Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;550 5.7.1 <me@newdomain.com>... Relaying denied
Remote system: dns;mail.newdomain.com
(TCP|151.164.30.29|36974|XX.XX.XX.XX|25) (tux.newdomain.com ESMTP
Sendmail 8.12.5/8.12.5; Fri, 3 Jan 2003 10:06:28 -0600)
from my MUA, and in the maillog on the mail server I get:
reject=550 5.7.1 <me@newdomain.com>... Relaying denied
The ISP has setup the IP to resolve to the newdomain name, and I had
them enter an MX record for the mailserver, but they don't have an entry
for reverse DNS. Doing a dig command:
]# dig newdomain.com ANY
; <<>> DiG 9.2.1 <<>> newdomain.com ANY
;; global options: printcmd

---------------------------------------------------------------------------------
I am new to setting up DNS, so my questions are:
1. Does the ISP need to setup reverse DNS and make an address entry for
nameserver1.newdomain.com.?
Or, should I setup DNS locally to do this?
2. If I setup DNS locally, how can I get incoming DNS queries to use my DNS?
Thanks for your help, in advance.
